CVSS v3.1 |
| ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is terminated with a NUL (0) byte. Although not a strict requirement, ASN.1 strings that are parsed using OpenSSL's own "d2i" functions (and other similar parsing functions) as well as any string whose value has been set with the ASN1_STRING_set() function will additionally NUL terminate the byte array in the ASN1_STRING structure. However, it is possible for applications to directly construct valid ASN1_STRING structures which do not NUL terminate the byte array by directly setting the "data" and "length" fields in the ASN1_STRING array. This can also happen by using the ASN1_STRING_set0() function. Numerous OpenSSL functions that print ASN.1 data have been found to assume that the ASN1_STRING byte array will be NUL terminated, even though this is not guaranteed for strings that have been directly constructed. Where an application requests an ASN.1 structure to be printed, and where that ASN.1 structure contains ASN1_STRINGs that have been directly constructed by the application without NUL terminating the "data" field, then a read buffer overrun can occur. The same thing can also occur during name constraints processing of certificates (for example if a certificate has been directly constructed by the application instead of loading it via the OpenSSL parsing functions, and the certificate contains non NUL terminated ASN1_STRING structures). It can also occur in the X509_get1_email(), X509_REQ_get1_email() and X509_get1_ocsp() functions. If a malicious actor can cause an application to directly construct an ASN1_STRING and then process it through one of the affected OpenSSL functions then this issue could be hit. This might result in a crash (causing a Denial of Service attack). It could also result in the disclosure of private memory contents (such as private keys, or sensitive plaintext). Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k). Fixed in OpenSSL 1.0.2za (Affected 1.0.2-1.0.2y). |
| Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i). Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x). |
| The default configuration of McAfee VirusScan 4.5 does not quote the ImagePath variable, which improperly sets the search path and allows local users to place a Trojan horse "common.exe" program in the C:\Program Files directory. |
| Directory traversal vulnerability in McAfee ASaP VirusScan agent 1.0 allows remote attackers to read arbitrary files via a .. (dot dot) in the HTTP request. |
| Buffer overflow in the (1) smap/smapd and (2) CSMAP daemons for Gauntlet Firewall 5.0 through 6.0 allows remote attackers to execute arbitrary code via a crafted mail message. |
| Format string vulnerability in McAfee Security ePolicy Orchestrator (ePO) 2.5.1 allows remote attackers to execute arbitrary code via an HTTP GET request with a URI containing format strings. |
| The default installation of MSDE via McAfee ePolicy Orchestrator 2.0 through 3.0 allows attackers to execute arbitrary code via a series of steps that (1) obtain the database administrator username and encrypted password in a configuration file from the ePO server using a certain request, (2) crack the password due to weak cryptography, and (3) use the password to pass commands through xp_cmdshell. |
| RAV antivirus allows remote attackers to bypass antivirus protection via a compressed file with both local and global headers set to zero, which does not prevent the compressed file from being opened on a target system. |
| Heap-based buffer overflow in ePO agent for McAfee ePolicy Orchestrator 2.0, 2.5, and 2.5.1 allows remote attackers to execute arbitrary code via a POST request containing long parameters. |
| Directory traversal vulnerability in ePO agent for McAfee ePolicy Orchestrator 3.0 allows remote attackers to read arbitrary files via a certain HTTP request. |
| Format string vulnerability in ePO service for McAfee ePolicy Orchestrator 2.0, 2.5, and 2.5.1 allows remote attackers to execute arbitrary code via a POST request with format strings in the computerlist parameter, which are used when logging a failed name resolution. |
| McAfee ePolicy Orchestrator agent allows remote attackers to cause a denial of service (memory consumption and crash) and possibly execute arbitrary code via an HTTP POST request with an invalid Content-Length value, possibly triggering a buffer overflow. |
| McAfee VirusScan 4.5.1 does not drop SYSTEM privileges before allowing users to browse for files via the "System Scan" properties of the System Tray applet, which could allow local users to gain privileges. |
| Computer Associates (CA) InoculateIT 6.0, eTrust Antivirus r6.0 through r7.1, eTrust Antivirus for the Gateway r7.0 and r7.1, eTrust Secure Content Manager, eTrust Intrusion Detection, EZ-Armor 2.0 through 2.4, and EZ-Antivirus 6.1 through 6.3 allow remote attackers to bypass antivirus protection via a compressed file with both local and global headers set to zero, which does not prevent the compressed file from being opened on a target system. |
| Eset Anti-Virus before 1.020 (16th September 2004) allows remote attackers to bypass antivirus protection via a compressed file with both local and global headers set to zero, which does not prevent the compressed file from being opened on a target system. |
| Entercept Agent 2.5 agent for Windows, released before May 21, 2002, allows local administrative users to obtain the entercept agent password, which could allow the administrators to log on as the entercept_agent account and conceal their identity. |
| Sophos Anti-Virus before 3.87.0, and Sophos Anti-Virus for Windows 95, 98, and Me before 3.88.0, allows remote attackers to bypass antivirus protection via a compressed file with both local and global headers set to zero, which does not prevent the compressed file from being opened on a target system. |
| Mcafee FreeScan allows remote attackers to cause a denial of service and possibly arbitrary code via a long string in the ScanParam property of a COM object, which may trigger a buffer overflow. |
| McFreeScan.CoMcFreeScan.1 ActiveX object in Mcafee FreeScan allows remote attackers to obtain sensitive information via the GetSpecialFolderLocation function with certain parameters. |
| McAfee Remote Desktop 3.0 and earlier allows remote attackers to cause a denial of service (crash) via a large number of packets to port 5045. |
