Detailsinfo

A vulnerability was found in Cyrus IMAPd 2.0.17/2.1.16/2.1.17/2.1.18/2.2.10. It has been classified as critical. Affected is an unknown code of the component fetch. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Multiple buffer overflows in Cyrus IMAPd before 2.2.11 may allow attackers to execute arbitrary code via (1) an off-by-one error in the imapd annotate extension, (2) an off-by-one error in "cached header handling," (3) a stack-based buffer overflow in fetchnews, or (4) a stack-based buffer overflow in imapd.

The weakness was shared 05/02/2005 (Website). The advisory is shared for download at security.gentoo.org. This vulnerability is traded as CVE-2005-0546 since 02/25/2005.
