Path‑Traversal Remote Code Execution Risk in Sophos SG UTM Email Proxy

A path traversal vulnerability allows a remote unauthenticated attacker to execute arbitrary code as root in Sophos UTM (all versions) after winning a race condition by sustaining repeated attacks for a few minutes when the email proxy is used with scanning enabled. Sophos UTM is end-of-life and the patch must be installed manually.

Local Privilege Escalation in Sophos Endpoint and Home for macOS Allows Arbitrary Code Execution as Root

A privilege escalation vulnerability allows local users to execute arbitrary code as root via Sophos Endpoint for macOS older than version 2026.1.1 and Sophos Home for macOS older than version 10.11.6.

ContentKeeper Web Appliance < 125.10 Arbitrary File Access via mimencode

ContentKeeper Web Appliance (now maintained by Impero Software) versions prior to 125.10 expose the mimencode binary via a CGI endpoint, allowing unauthenticated attackers to retrieve arbitrary files from the filesystem. By crafting a POST request to /cgi-bin/ck/mimencode with traversal and output parameters, attackers can read sensitive files such as /etc/passwd outside the webroot.

OpenSSH: Client buffer-overflow when using roaming connections

The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings.

OpenSSH: Client Information leak due to use of roaming connection feature

The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key.

The installation of Sophos PureMessage for Microsoft Exchange 3.0 before 3.0.2, when both anti-virus and anti-spam are supported, does not create or launch the associated scan engines when the system is under heavy load, which has unspecified impact, probably remote bypass of scanner protection or a denial of service (message loss or delay).

Sophos Anti-Virus 4.33.0, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.

Multiple unspecified vulnerabilities in Sophos SAVScan 4.33.0 for Linux, and possibly other products and versions, allow remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via crafted files that have been packed with (1) armadillo, (2) asprotect, or (3) asprotectSKE.

Multiple cross-site scripting (XSS) vulnerabilities in the web administration interface in Sophos ES1000 and ES4000 Email Security Appliance 2.1.0.0 allow remote attackers to inject arbitrary web script or HTML via the (1) error and (2) go parameters to the login page.

The virus detection engine in Sophos Anti-Virus before 2.49.0 does not properly process malformed (1) CAB, (2) LZH, and (3) RAR files with modified headers, which might allow remote attackers to bypass malware detection.

Sophos Anti-Virus 7.0.5, and other 7.x versions, when Runtime Behavioural Analysis is enabled, allows local users to cause a denial of service (reboot with the product disabled) and possibly gain privileges via a zero value in a certain length field in the ObjectAttributes argument to the NtCreateKey hooked System Service Descriptor Table (SSDT) function.

Sophos Anti-Virus for Windows before 7.6.3, Anti-Virus for Windows NT/9x before 4.7.18, Anti-Virus for OS X before 4.9.18, Anti-Virus for Linux before 6.4.5, Anti-Virus for UNIX before 7.0.5, Anti-Virus for Unix and Netware before 4.37.0, Sophos EM Library, and Sophos small business solutions, when CAB archive scanning is enabled, allows remote attackers to cause a denial of service (segmentation fault) via a "fuzzed" CAB archive file, as demonstrated by the OUSPG PROTOS GENOME test suite for Archive Formats.

Sophos PureMessage Scanner service (PMScanner.exe) in PureMessage for Microsoft Exchange 3.0 before 3.0.2 allows remote attackers to cause a denial of service (message queue delay and incomplete spam rule update) via a crafted (1) RTF or (2) PDF file.

Sophos PureMessage for Microsoft Exchange 3.0 before 3.0.2 allows remote attackers to cause a denial of service (EdgeTransport.exe termination) via a TNEF-encoded message with a crafted rich text body that is not properly handled during conversion to plain text. NOTE: this might be related to CVE-2008-7104.

Cross-site scripting (XSS) vulnerability in Sophos Anti-Virus for Windows 6.x before 6.5.8 and 7.x before 7.0.1 allows remote attackers to inject arbitrary web script or HTML via an archive with a file that matches a virus signature and has a crafted filename that is not properly handled by the print function in SavMain.exe.

Sophos Anti-Virus for Unix/Linux before 2.48.0 allows remote attackers to cause a denial of service (infinite loop) via a malformed BZip file that results in the creation of multiple Engine temporary files (aka a "BZip bomb").

Sophos Anti-Virus and Endpoint Security before 6.0.5, Anti-Virus for Linux before 5.0.10, and other platforms before 4.11 allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via a malformed CHM file with a large name length in the CHM chunk header, aka "CHM name length memory consumption vulnerability."

Sophos Anti-Virus 5.1 allows remote attackers to cause a denial of service (memory consumption) via a file that is compressed with Petite and contains a large number of sections.

Sophos Anti-Virus and Endpoint Security before 6.0.5, Anti-Virus for Linux before 5.0.10, and other platforms before 4.11, when "Enabled scanning of archives" is set, allows remote attackers to cause a denial of service (infinite loop) via a malformed RAR archive with an Archive Header section with the head_size and pack_size fields set to zero.

Heap-based buffer overflow in Sophos Anti-Virus and Endpoint Security before 6.0.5, Anti-Virus for Linux before 5.0.10, and other platforms before 4.11, when archive scanning is enabled, allows remote attackers to trigger a denial of service (memory corruption) via a CHM file with an LZX decompression header that specifies a Window_size of 0.
